rhythm and lead have same tone but different tone volumes

[Xstatic]

I just made a custom and the lead arrangement and rhythm use the same tone but in game the lead is quiet and the rhythm is the correct volume.  How is this possible?  How do I make the lead the same volume as the rhythm I didn't even know it was possible to have them be different volumes for same tone in the same custom.

save the tone with volume, name it tone v1 and save it again with different volume named tone v2 and treat them as two different tones

Thanks I will try that.
